ROW Flash, and Now Car Is Undrivable!

Make sure the second plug from the top is clean and seated properly on the DME.

Paul -Thank you for the feedback, but that looks like some Durametrics screens, which I don't own. My Autel is not that smart.

Gave it one last try. Warmed the car up as before, noted the same problem. Shut off car, disconnected the battery, and removed the ECU. All of the 5 connectors had been seated well. Looked for bent pins or some other mechanical problem - nothing. Gently cleaned the pins with an old toothbrush and electrical contact spray cleaner, and flushed the pin's receptacles with the spray. Did not see any signs of mischief.

Reinstall ECU, triple check that all connectors are well seated. Plug in battery, and do the throttle reinitiation again with the engine in the proper temp range. Start car. No changes. Same old same old.

Sigh.

At this point, I am done fussing with it on my own, as I am comfortable that whatever it is, it's not an installation fault which I have created.

ECU Doctors discussion tomorrow.

Thanks again for your ears - DM

It's not a Durametrics screen it's a PST 2 screen.

The ECU, immobilizer, and keys will be sent back to Florida tomorrow, so to allow the ECU Doctors to have a thorough review.

I remain quite confident that they'll be able to sort it, so fingers crossed.

Thanks - DM

I have just heard back from the ECU Doctors.

They discovered a "software problem" present in the ECU, such that the ROW reflash "did not properly take".

I am assured that it has been all sorted now, and it has been shipped back to me, likely to arrive here the middle of next week or so.

Here's hoping that I can post a final wrap-up, once received and installed.

Thanks - DM
